What are the two basic types of optical fibers?

The identification of multimode and single mode as the two basic types of optical fibers is accurate because these classifications are based on the way light travels through the fibers.

Multimode fibers allow multiple light modes to propagate simultaneously. They have a larger core diameter, which means that the light can bounce around inside the core at different angles, making them suitable for short-distance communication applications such as within buildings or campuses.

Single mode fibers, on the other hand, have a smaller core diameter that permits only one mode of light to propagate, significantly reducing modal dispersion. This characteristic enables single mode fibers to transmit data over much longer distances with higher bandwidth capabilities, making them ideal for telecommunication applications.

The combination of these two types reflects differing uses and performance characteristics pertinent to their design and optical properties, which is integral for understanding fiber optics in communication and data networks.
